升温速率对卷烟烟丝快速热解的影响
Effects of heating rate on fast pyrolysis of cut filler of cigarette
摘要
Abstract
In order to study the effects of heating rate on fast pyrolysis of cut filler of cigarette, TGA (Thermogravimetric Analyzer) combined with QMS (Quadrupole Mass Spectrometers) was applied to investigate the pyrolysis characteristics of cut filler of cigarette at different heating rates (200 K·min-1-800 K·min-1), and a kinetic model for the fast pyrolysis of cut filler at different heating rates was developed. The results showed that: 1) With the increase of heating rates, thermal decomposition overlap region, mass loss rate and devolatilization index of each main component in tobacco were raised. Meanwhile, thermal lags of different extents were also observed. 2) The kinetic model overcame the deviation of kinetic parameters caused by thermal lag via introducing a heating rate correction factor, and predicted the fast pyrolysis behaviors of cut filler at different heating rates more accurately. 3) The release of pyrolysis products, such as acrolein (m/z=56), pyridine (m/z=79), nicotine (m/z=84), phenol (m/z=94) and indole (m/z=117) decreased with the increase of heating rate. The fast pyrolysis characteristics of cut filler are closer to the real state of cigarette combustion and the developed mathematical model for tobacco pyrolysis kinetics is more accurate at high heating rate.关键词
